First ICESat-2 Global Data Released: Ice, Forests and More

Iowa Climate Science Education

From NASA Global Climate Change

To assess the accuracy of the newly released ICESat-2 data, a NASA team set out to the South Pole. For the second-straight year, the team endured below-freezing temperatures, biting winds, and high altitude to conduct a traverse along the 88 degree south latitude line, taking highly accurate GPS measurements to compare with those from the satellite.

More than a trillion new measurements of Earth?s height ? blanketing everything from glaciers in Greenland, to mangrove forests in Florida, to sea ice surrounding Antarctica ? are now available to the public. With millions more observations added each day, data from NASA?s Ice, Cloud and land Elevation Satellite-2 is providing a precise global portrait of elevation and will allow scientists to track even the slightest changes in the planet?s polar regions.

?The data from ICESat-2 are…
